Frequently Asked Questions
Lug Type valves have threaded inserts that allow them to be bolted directly to the flange, enabling them to be used for dead-end service, whereas Wafer Type valves are sandwiched between two flanges.
For higher temperature and chemical resistance, PTFE or Viton seats are recommended over NBR or EPDM.
Yes, by selecting the Stainless Steel (ASTM A351 CF8/CF8M) disc and stem options, the valve is well-suited for corrosive media.
The Model 30 is available in sizes ranging from 2 inches (50mm) up to 12 inches (300mm).
The long neck allows for easier access to the actuator or handle in congested piping layouts and provides better clearance for insulation.
Yes, we utilize ASTM standards for all core materials, including ASTM A126 for cast iron and ASTM A536 for ductile iron.
